 From what I've read of this thread it seems that you have a linux 
system installed on /dev/hdb1 and a windows boot loader on the boot disk.

I suggest that you try to boot /dev/hdb1 from a grub floppy to test if 
you have a credible linux system installed. If you don't have a grub 
boot floppy, the easiest way to get one is to boot from a knoppix cd, 
put a formatted floppy in the drive and type grub-floppy.
